The genes are composed of DNA and are carried on the chromosomes. Genes direct the production of all the molecules that form the structures that of a cell. Genes determine the inherited characteristics that distinguish one individual from another. Each human has an estimated 90,000 genes.
HIV vaccine failure probably caused by virus used, says new research – The recent failure of an HIV vaccine was probably caused by the immune system reacting to the virus ‘shell’ used to transmit the therapy around the body, revealed by researchers.
Reduced muscle strength associated with risk for Alzheimer’s disease – Individuals with weaker muscles appear to have a higher risk for Alzheimer’s disease and declines in cognitive function over time, revealed by the researchers.
‘Genome 10K’ proposal aims to sequence 10,000 vertebrates – An international group of scientists is proposing to generate whole genome sequences for 10,000 vertebrate species using technology so new it hasn’t yet been invented.
Diabetes weakens your bones – The inflammatory molecule TNF-a may contribute to delayed bone fracture healing in diabetics, revealed by researchers. Diabetes, a condition where the body either does not produce enough, or respond to, insulin, affects at least 171 million people worldwide, a figure that is likely to double by 2030.
